IMPROVEMENT IN LAMP-BURNERS.

To all whom it may concern:

Be it known that I, J. K. ANDREWS, of Antrim, in the'county of Guernseyand State of Ohio, have invented anew and Im proved Lamp- Burner; and Ido hereby declare that the followingI is a'full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being` had to the accompanying drawing,forming part of this specification.

The drawing represents a vertical central section of this invention.

This invention relates to a lamp-burner of that class in which the oilis vaporized before it is burned. It is composed of two perforatedtubes, one within the other, and elevated above the lamp-top in such amanner that an ample supply of air is admit ted, and the several partsare prevented from being;` overheated. Both the inner and .outer tubesare provided with slotted caps, and the bottom end of theinner tube isperforated with large openings, so that a current of air passes to theflame from the inside as well as from the outside, and the gas or vaporproduced by the oil is readily consumed,formin gabrilliantame withoutsmoke.

A represents my burner, which is composed of two tubes, B O, one insidethe other, and supported by a chamber, D, which is elevated at somedistance above the screw-cap E of the lamp, and which is supported bythe wick-tube F and vent-tube I. Y

The tubes B O and the chamber D are made of perforated sheet metal, sothat the air has free access to all the parts, a-nd the wick-tube Fterminates in the lower portion of the inner tube, O, as clearly shownin the drawing. That portion of the tube O which surrounds the upper endof the wick-tube is perforated with large openings, so as to admit anample supply of air, and both the tubes B and O are provided withslotted caps Gr H.

The vapor formed by the oil in the wicktube is mixed with a largequantity of atmospheric air in the inner tube, O, and as this mixturereaches the slotted cap H an additional supply of air is carried to itby the cap Gr, and a brilliant flame is produced free from smoke.

I disclaim everything` claimed in a patent granted to me July 11, 1865;but

What I claim as new, and desire to secure by Letters Patent, is-

A lamp-burner composed of two perforated tribes, B O, with caps Or H, incombination with the perforated chamber D, wick-tube F, and vent tube I,constructed and operating substantially as and for the purpose setforth.
